Hi @usama_seo,

Can you check the excpetion.log to see if there is an error with more information?

Hi @usama_seo,

Can you share the whole configuration?

It seems the request is not working properly.

Hi @usama_seo,

I'm not sure but I guess the problem is the other end. The system where you want to connect.

Maybe is an url that starts with: "https://qumuru..." ?

That's why I've asked if you was able to share the integration details. Can you check again if that data is ok and the URL is accesible for Magento?
